GPT-5 arrives in Microsoft Copilot as an intelligent ally

The artificial intelligence revolution keeps moving forward, and today marks a new milestone: GPT‑5, OpenAI's most advanced system, is now available in Microsoft 365 Copilot and Copilot Studio. This new version represents a significant leap in intelligence and promises to change the way people work, automate tasks and make decisions.

Since its launch, Microsoft committed to integrating OpenAI's latest models into Copilot in less than 30 days. And it is delivering on that. GPT-5 arrives with improvements that make it faster, more accurate and able to understand the work context. All of this without losing sight of the security, privacy and compliance that characterize Microsoft.

What makes GPT-5 different in Copilot?

For the first time, Copilot can understand a request and use the GPT-5 real-time router to choose the most suitable model. This means it does not just answer, it reasons based on the type of question.

• For simple or routine questions, Copilot uses a fast and efficient model that delivers clear, concise answers.
• For more complex requests, it detects that deep reasoning is needed and activates the advanced GPT-5 model, which analyzes the context, plans and verifies before responding.

This intelligent approach allows Copilot to act as a true digital assistant, adapting to each situation the way a person would.

Intelligence that adapts to real work

Imagine that a marketing team is evaluating agency proposals. Copilot can look up the answers, summarize them and deliver a clear list. But if it is asked to analyze and rank those proposals, it recognizes that this is a more complex task. It then accesses documents, emails, meetings and chats to offer a well-grounded recommendation.

This "dual mode" of GPT-5 — fast and deep — is what makes it a powerful tool for companies looking for efficiency without losing quality.

Available starting today

GPT‑5 is now available for users with a Microsoft 365 Copilot license, who will be able to use it to analyze both web and work data (emails, documents, meetings, etc.). They only need to turn on the "Try GPT-5" button in Copilot Chat. Users without a license will also begin receiving access in the coming weeks.

In addition, GPT-5 is integrated into Copilot Studio, the platform for building custom agents. Starting today, you can select GPT-5 as the main model and use it in more ambitious business processes.

And what about Researcher?

Although GPT-5 improves Copilot on complex day-to-day tasks, Researcher remains the ideal agent for deep research work. If you need an exhaustive analysis across multiple sources, Researcher is the option. It is perfect for high-level reports, competitive analyses or client preparation.

What kinds of requests can you try?

For users with a Microsoft 365 Copilot license:

• "Analyze my recent emails and chats and describe my communication style, values, strengths and areas for improvement."
• "Update me on the plans for the [name] project and help me decide the next steps."
• "Write a 'lessons learned' summary about the [name] project."
• "Calculate how many hours I have worked on GPT-5 over the last 5 days."

For all users, even without a license:

• "Review the attached project plan and suggest five improvements with justification and specific wording."
• "Turn this customer feedback sheet into an executive report for senior leadership."
• "Compare our press release with similar ones and suggest how to stand out."
• "As a financial compliance analyst, summarize the differences between Dodd-Frank, Basel III and MiFID II."

GPT-5 in Copilot does not just answer, it thinks, analyzes and adapts. It is the beginning of a new era in the intelligent automation of work. Is your company ready to take advantage of it?
